(ACTIVE) Delfino Microcontroller


Functional diagram


The TMS320C2834x (C2834x) Delfino™ microcontroller (MCU) devices build on TI's existing F2833x high-performance floating-point microcontrollers. The C2834x delivers up to 300 MHz of floating-point performance, and has up to 516KB of on-chip RAM. Designed for real-time control applications, the C2834x is based on the C28x™ core, making it code-compatible with all C28x microcontrollers. The onchip peripherals and low-latency core make the C2834x an excellent solution for performance-hungry realtime control applications.
